Whether you spilt a can of paint on your concrete floor or just need to remove old paint before sealing or staining, chemical products can assist you. Though you can try using a pressure washer to remove paint from exterior surfaces, chemical agents are an effective alternative. Work in a well-ventilated area and wear gloves and protective eye wear when working with chemicals. Several soy-based products are also available, though you should still exercise caution and take protective measures.

Behr Concrete & Masonry Paint Stripper No. 992

Behr's Concrete Stripper can be used on interior and exterior surfaces such as basement and garage floors, patios, walkways, driveways, and concrete walls. Use the stripper to remove sealants, latex, stains, and more, including most other paints. You should be able to cover approximately 60 to 75 square feet per gallon of paint stripper. One gallon of stripper retails for £17.8 as of December 2010. Behr Concrete & Masonry Paint Stripper is biodegradable, but you should contact your refuse collection service for information on proper disposal. Although most paints will take between 1 and 6 hours to remove, be sure to perform a patch test on the area you are stripping to determine the correct stripping time.

Lightening Strip Paint and Mastic Remover

Lightening Strip Paint and Mastic Remover strips multiple layers of paint from concrete with only one application by causing the bottom layer of paint to expand and weaken its adhesion to the concrete. It can be used with water and oil-based paints, acrylic paints, primers and more and, because it gels to the surface as it is applied, it can be used for vertical surfaces as well. Lightening Strip will also remove waterproofing paint, but will not remove silicon-based sealers. The stripper is applied with a non-aerosol spray rather than a brush and the paint residue from Lightening Strip can be cleaned with only water. You will be able to cover approximately 150 square feet per gallon of Lightening Strip for 1 to 2 layers of paint and approximately 75 square feet per gallon with 2 to 4 layers of paint. One gallon of stripper is sold for £24 as of December 2010.
